[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 7 , is a packaging box clamping structure according to an embodiment of the present invention, comprising a carrying assembly 10 and clamping assemblies 20 mounted on opposite side edges of the carrying assembly 10 .

[0030] The carrier assembly 10 includes a carrier plate 11 and two positioning plates 12 detachably mounted on the top surface of the carrier plate 11. The positioning plates 12 are separated by cavities 13 for positioning and accommodating the packaging boxes. Fixed clamps 14 are protruded from the inner side of the top surface of each positioning plate 12 at intervals, and are designed to abut against the packaging boxes.

[0031] In this embodiment, if Figure 1 and Figure 2As shown, guide holes 15 are provided on opposite sides of the middle portion of the carrier plate 11 for easy placement on the production line. Identification cavities 16 are provided on opposite sides of the middle portion of the carrier plate 11 for placement of identification elements such as QR codes to facilitate matching and identification during production.

[0032] In this embodiment, the bearing assembly 10 further includes an anti-collision pad 17 correspondingly disposed on one side of each clamping assembly 20 . The anti-collision pad 17 is installed on the edge of the bearing plate 11 .

[0033] The clamping assembly 20 includes a fixed base 21 fixedly connected to the edge of the carrier plate 11, a movable clamping block 22 slidably connected to the top surface of the fixed base 21, drive wheels 23 rotatably mounted on opposite sides of the movable clamping block 22, a stopper 24 mounted on the side of the movable clamping block 22 facing away from the carrier plate 11, a spring 25 sandwiched between the movable clamping block 22 and the stopper 24, a guide post 26 mounted on one side of the movable clamping block 22, and a wedge block 27 slidably engaged with the guide post 26; the inclined surface of the wedge block 27 abuts the drive wheel 23 downward. The stopper 24 is connected to the fixed base 21, and the movable clamping block 22 is located outside the positioning plate 12. The spring 25 drives the movable clamping block 22 to always move toward the fixed clamping block 14, so that the movable clamping block 22 and the fixed clamping block 21 can clamp the packaging box. Compared with the traditional fixed-design packaging box clamping and positioning structure, the utility model uses a spring 25 to drive the movable clamping block 22 to always move toward the fixed clamping block 14, which can adapt to packaging boxes of different sizes, greatly improving the flexibility and versatility of clamping, eliminating the need for repeated mold replacement, and effectively reducing time costs.

[0034] Specifically, the movable clamping block 22 moves in a direction parallel to the top surface of the positioning plate 12, and the wedge block 27 slides in a direction perpendicular to the top surface of the positioning plate 12. In actual use, pressing the wedge block 27 causes the inclined surface of the wedge block 27 to contact the drive wheel 23, thereby pushing the movable clamping block 22 away from the positioning plate 12, that is, pushing the movable clamping block 22 away from the fixed clamping block 14, thereby facilitating the removal and placement of packaging boxes.

[0035] Furthermore, if Figure 4 and Figure 5 As shown, a soft pad 28 is installed on the side of the movable clamping block 22 facing the fixed clamping block 14 to avoid rigid contact with the surface of the packaging box and prevent damage to the surface of the packaging box.

[0036] In this embodiment, the end of the movable clamp 22 facing the stopper 24 is provided with an inner cavity 220. A positioning post 240 is protruding from the side of the stopper 24 facing the movable clamp 22. The positioning post 240 is coaxially arranged with the inner cavity 220. One end of the spring 25 is sleeved with the positioning post 240, and the other end of the spring 25 is inserted into the inner cavity 220. This allows the spring 25 to be securely clamped between the movable clamp 22 and the stopper 24, ensuring stable movement.

[0037] The above-mentioned packaging box clamping structure has a simple structure and is easy to use. The inner side of the positioning plate 12 is connected to the fixed clamping block 14, and the outer side of the positioning plate 12 is connected to the clamping assembly 20. The spring 25 is used to drive the movable clamping block 22 to always move toward the fixed clamping block 14. It can adapt to packaging boxes of different sizes, greatly improving the flexibility and versatility of clamping, eliminating the need for repeated mold replacement, and effectively reducing time costs.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
